FIG. 4 shows a process executed by the in-vehicle controller 14 of the in-vehicle device 2.

First, the vehicle-mounted control unit 14 authenticates the mobile terminal 3 (step S1). Specifically, the vehicle-mounted control unit 14 intermittently sends out a request signal for the terminal identification information. By disposing the mobile terminal 3 in the communicable area A, the mobile terminal 3 receives the request signal of the terminal identification information, and the mobile terminal 3 that has received the request signal transmits the terminal identification information to the vehicle-mounted apparatus 2. The vehicle-mounted control unit 14 collates the received terminal identification information with the authentication information stored in the vehicle-mounted control unit 14, and authenticates the mobile terminal 3 when the terminal identification information and the authentication information match. The authentication result is transmitted to the mobile terminal 3.

The vehicle-mounted control unit 14 that succeeds in the authentication of the mobile terminal 3 (step S2-Yes) waits until the instruction information transmitted from the mobile terminal 3 is received, and receives the start instruction of the drive system of the vehicle V as the instruction information. Then, (step S3-Yes), the drive system of the vehicle V is started using the function of the drive system electronic control unit 10 of the vehicle V (step S4).

Here, the straight-ahead permissible range refers to a range of the steering angle at which the vehicle V can be regarded as going straight.

Further, the openable position of the driver's seat door is set by, for example, the moving amount of the vehicle V, and the moving amount is registered in advance in the vehicle-mounted control unit 14 or the terminal control unit 42. The amount of movement is not particularly limited, but is, for example, the total length of the vehicle V. In addition, the amount of movement in the case of forward movement is defined as the distance from the front end of the vehicle V to the rear end of the driver's door, and the amount of movement in the case of reverse movement is defined as the distance from the rear end of the vehicle V to the front end of the driver's door. Different movement amounts may be set depending on the case and the backward movement.

The openable position of the driver's seat door may be adaptively set based on the position of the user who holds the mobile terminal 3, and for example, the driver's seat door is a position aligned with the user in the vehicle width direction. .. The positional relationship between the driver's seat door and the user uses, for example, the property that the radio field intensity of the signal attenuates in inverse proportion to the distance (distance attenuation), and the radio wave of the signal transmitted from the mobile terminal 3 and received by the vehicle-mounted device 2 is used. It can be detected based on the strength and the positional relationship between the antenna 30 of the vehicle-mounted apparatus 2 that has received the signal and the driver's seat door.

Further, in this example, the seating detection unit 13 detects the seating of the occupant in the driver's seat, and the in-vehicle control unit 14 receives the seating detection signal output from the seating detection unit 13 (step S12-Yes), The door opening/closing part 12 is controlled to close the driver's seat door (step S13).
